Abstract

An earlier paper described an algorithm for power system state estimation exploiting decoupling between active and reactive equations and including an estimation of regulating transformer ratios. An improvement which avoids repeatedly calculating the gain matrices is described. Execution times are decreased by up to 80 percent.
